Application filed July 6, 1928, Serial No. 290,839, and in Germany August 22, 1927.

. This inventionrefers broadly to paperand Y card-board cutting machines and the like, and it is particularly intended to provide means incombination with such machinesfor the movement of the pile of leaves as a unit, and for automatically truing the pile in the cutting plane,so that no parts of the piIe Wlll I project or recede from said cutting plane,

and the invention is further intended to fal cilitate and simplify the manipulation of devices of this kind, and to obtain a sharply defined plane at the outside of the pile without; any complicated and difficult corrections. Infconnection therewith itis a further 1mportant object of this invention to so improve the feeding of the pile that the movement of the stop or follower may be facilitated and accelerated, and a considerably increased output may thereby be produced.

3 With the means disclosed by the previous art and intended for instance to impart "to the stop automatically a reciprocating and feeding movement, the pile of sheets to be cut could only be moved in the forward direction,

while it was left behind during the return movement of the stop, and had to be pushed back by handuntil it was caused to engage and impinge against the stop. This was not i only a very di cult and troublesome operation, but it also failed to yield-accurate results. Nor was it possible with this arrangement to connector secure the pile to. the stop,

may comprise a piece of sheet metal secured to the stop which is preferably roughened on its upper surface and polished at the bottom surface. The invention is shown by way" of exemplification upon the accompanying drawing as applied to acutting machine, em-

bodyin this invention in Figure 1 in side view and in igure 2 in plan view. Figure 3 repstance in Figure 1 of the drawing.

carried along with the stop in the return movementthereof. This supporting surface resents on an enlarged scale a sectional View through a part of the cutting machine.

The stop 3 is operated in the usual manner by means of the quick-acting stop operating wheel. By means of screws 2 and a pressureplate or washer 3 the stop is connected to a plate 1 of sheet metal which .is bent angularly and rests on the cutting table with one of its legs. Upon the sheet metal plate 1 the cutting card-board 4 is disposed which is commonly employed .for' the saving of the cutting bars 5 and for the purpose of facilitating the manipulation ofthe pile 6. The plate '1 is preferably of such length that even the longest kind of pile will be supported uponjfi the plate with substantially two thirds of itslength, while one third of the len th of the pile projects therefrom. Inview t ereof the pile 6 will rest with perfect safety upon the plate 1, so that it may be carried along with the plate'l in its movement. The sheet metal plate 1 may be of but limited thickness, thus for instance about one-eightieth of an inch (0.3 millimeters). In view of the small thickness this sheet-metal plate will not interfere with the cut,-even in case its front edge should happen tobe positioned shortly beyond the cutting plane, as shown for 'in- As a material for the plate 1 a brass-sheet '80 I maypreferably be employed having a substantially rough upper surface and a polished 4 under surface. By this means the friction .which otherwise occurs between the cutting in front on the plate and thenthe stop is returned in the known manner either by hand or by machine. The stop 3-now carries the plate 1 and the latter the pile, whereby a is.

brought into its rearposition. As soon as the pile is withdrawn below the knife to the extent to which it has to be cut off, the stop is stopped and the cutting device operated. Inasmuch as various modifications may be made in the construction and arrangement shown within the principle and scope of this invention, the invention should not be limited to the specific structure shown-and described, except as appears from the appended claim.

I claim In a paper and card board c'uttin machine, the combination with a cutting ta 1e and an upright truing and supporting stop movably disposed on said table of a thin supporting plate for receiving a pile of papers to be out, having a rough upper surface and a substantially polished lower surface, the inner end of the plate being angularly secured to the stop so that the plate extends in parallelism with and rests on the table and is movable with said stop substantially as and for the purposes set forth. In testimony whereof I afiix my signature. KARL STEGMANN.
